Use dev_dbg() instead of dev_err() in pcie_advk_check_pio_status().
For example CRS is not an error status, it just says that the request
should be retried.
Without this, U-Boot spams the terminal with
pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x100000
pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x108000
pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x110000
pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x120000
pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x128000
pcie_advk pcie@d0070000: Non-posted PIO Response Status: UR, 0xc80 @ 0x130000
...
when a device is not connected to a PCIe switch (Unsupported Request
from the switch).
